Snoring is caused by the narrowing of the upper airway and poor airflow during breathing.

Snoring has many hazards. First of all, patients have poor sleep quality, experience difficulty breathing, and may have breathing pauses. This can cause severe oxygen deficiency in the brain and blood, leading to hypoxemia, and can also trigger high blood pressure, myocardial infarction, and cerebrovascular diseases.

Therefore, it is best for patients to go to the hospital to have a polysomnogram to confirm the condition.
